Infuse Pro 4.1, iPad Pro and smb share.....not working

I’ve already tried any possible combination to make infuse pro 4.1 on my iPad Pro 12.9 see my Qnap smb share:

  • I used different account with different privileges, read only, read write or even guest
  • I tried to setup different smb protocol version 2.0 and 3.0

Infuse pro continues spinning the waiting circle whenever I try to browse my Qnap share via smb.
I can instead browse the same smb share with my iPad Pro using other apps. Thus it’s not a configuration problem of my share neither an iPad Pro general issue. It seems to be something with infuse pro.

Anyone else having the same problem?
